I think it's too early to bet on improving Chelsea's performance next season, because in general the season hasn't started yet and the Chelsea team themselves also still need to target other great players to enable them to display extraordinary performances next season. Because Chelsea also needs to see how to train and the performance of the new coach next season for Chelsea players who are really expected to bring very significant changes to the entire Chelsea team.
Pre match has not yet started but people already talked how big improvements gonna happen with chelsea. Some players like nkuku, jackson needs to build their chemistry with another player.
That being said that if it's still too far to think if chelsea will be having so many improvements. We shall at least see the result from pre match and we can take conclusion whether chelsea has made some improvements or it's still stagnant at this moment.
Im feeling doubtful with the performance from chelsea this season even though club has bought some talented players.
